The Belgian striker has spent the second half of the season on loan at Borussia Dortmund, scoring seven times in 10 league appearances.

Dortmund are ready to press on and make the deal permanent as they seek a full-time replacement for Pierre-Emerick Aubameyang, who moved to Arsenal in January.

Chelsea rejected Dortmund's request to have an option to buy in the loan agreement when it was signed, meaning Chelsea are free to negotiate a larger fee.

Stamford Bridge chiefs paid £33million for his signature in the summer of 2016 but he has failed to replicate the form he showed at Marseille in England.

Dortmund chief executive Hans-Joachim Watzke confirmed as early as four weeks into Batshuayi's loan spell that they would try and sign the striker permanently.

Batshuayi has almost definitely played his last game of the season after picking up an ankle injury.

He is now a major doubt for this summer's World Cup, where he would compete against England in Group G.

The 24-year-old posted on his social media channels earlier this week: "Well its not good news for now, my season is probably over, and I wont be able to pay @bvb09 back for their confidence."

Borussia Dortmund also confirmed the news and tweeted: "@mbatshuayi has suffered an ankle injury in the derby at @s04 and is likely to be out for the rest of the season. Playing for the Belgian national team at the World Cup in Russia is possible. Get well soon, Michy!"
